To use a wildcard character within a pattern: Open your query in Design view. In the Criteria row of the field that you want to use, type the operator Like in front of your criteria. Replace one or more characters in the criteria with a wildcard character. For example, Like R? On the Design tab, click Run. Click to see full answer. Simply so, what’s a wildcard in access?Wildcards are special characters that can stand in for unknown characters in a text value and are handy for locating multiple items with similar, but not identical data. Access supports two sets of wildcard characters because it supports two standards for Structured Query Language. which of the following wildcard characters does access use in validation rules to match any number of characters? ANSI-89 wildcard characters Character Description [ ] Matches any single character within the brackets. ! Matches any character not in the brackets. – Matches any one of a range of characters. You must specify the range in ascending order (A to Z, not Z to A). # Matches any single numeric character. Thereof, what is the wildcard character in a SQL query? To broaden the selections of a structured query language (SQL-SELECT) statement, two wildcard characters, the percent sign (%) and the underscore (_), can be used. The percent sign is analogous to the asterisk (*) wildcard character used with MS-DOS.What is a wildcard used for?Alternatively referred to as a wild character or wildcard character, a wildcard is a symbol used to replace or represent one or more characters. The most common wildcards are the asterisk (*), which represents one or more characters and question mark (?) that represents a single character. Show Related PostsAccess has powerful tools to cull the information you need from your databases. In a table or form, you use the Find command or a filter. In a query, you enter expressions on the design grid to retrieve records from the underlying tables. Often when we search for records, however, we�re not exactly sure what we�re looking for. For example, even after reading about the accounting firm Arthur Andersen for several months, many people still spelled Anders en as Anderson. But if you wanted Andersen and searched for Anderson, Access would not consider it a match; in other words, it would not find Andersen. So how do you find values in a table, form, or query when you�re unsure about the exact spelling? You use wildcards. For example, if you searched for Anders?n, Access would return all instances of both Anderson and Andersen, as well as any occurrence of Andersin or even Andersxn. That�s because you can use the question mark (?) wildcard to stand in for any alphanumeric character. Access would not find values such as Andersohn, however, because the question mark wildcard can substitute for only one character, not two or more. Wildcards are useful not only for finding information when you don�t know an exact spelling (or an exact number), but also for finding a range of values. For example, suppose you were searching a field with three-character product codes for any code that begins with A and ends with J. You could search for A?J to find these codes. There are other wildcards you can enter to satisfy your search requirements. Let�s take a look at using wildcards with the Find command in a form and then with expressions in queries.  Open the Northwind.mdb database in the Samples subfolder of your Microsoft Office folder. Assuming you have made a copy (or have a backup) of the Northwind database, open the file. In the Database window, click the Forms button. Double-click the Products form to open it. Suppose you were looking for any records for gnocchi, those delicious Italian dumplings. You know the word ends in chi and has noin it somewhere, but that�s the extent of your spelling guesswork. You can use the Find command with wildcards in your search term to locate it. Click in the Product Name field of the first record. Click the binoculars icon on the Form View toolbar to open the Find And Replace dialog box. On the Find tab, click in the Find What box. Because you don�t know the number of letters preceding the no and chi, in your search term you�ll use the asterisk (*) wildcard, which can stand in for any number of alphanumeric characters. Type *no*chi. The Look In field should read Product Name. Open the Match drop-down menu, choose Any Part Of Field, and click Find Next. In the Products form, Access jumps to Product ID 56, the record for Gnocchi di nonna Alice. Click Find Next to see if there are any other values for this search term. Click OK in the message that tells you there aren�t any. Click Cancel in the Find And Replace dialog box and close the Products form. In the Database window, click the Queries button and click New. In the New Query dialog, with Design View selected, click OK. In the Show Table dialog box, double-click the Customers table to add it to the grid. Close the Show Table dialog box (click Close). Maximize the query window. In the Customers field list, double-click CompanyName, ContactName, ContactTitle, and Phone to add these fields to the design grid. Suppose you wanted to create a query that showed all customers whose names begin with H, I, J, K, or L.You could use the brackets ([]) and hyphen wildcards to stand in for any of these letters. On the Criteria row of the CompanyName field, type Like. This operator tells Access you�re searching for values that match the following expression. Next, tap the spacebar once and type "[h-l]*�. The [h-l] portion tells Access to search for any letter, H through L; the asterisk means, as we�ve seen, that any number of characters may follow. The entire expression you�ll type is Like "[h-l]*�. Click View to see all customers that begin with the letters H through L. If you want to see records of customers whose first letters are not sequential, simply type each letter within the brackets. For example, to see records of companies that begin with letters H and Q, you would type the expression Like "[hq]*�. Finally, let�s say you want to see all customers whose names don�tbegin with letters H through L. You can use the exclamation point to retrieve these records. Click View. In the expression on the Criteria row of the CompanyName field, click before the H and type !. The expression you�ll want to type now is Like "[!h-l]*�. Click View. All of the records except those that begin with this range of letters are displayed. Close the query. If you decide to save it for future reference, be sure to give it a name, such as Smart Computing Wildcards, so you know it isn�t part of the original Northwind database. Which wildcards can you use in a query?Examples of wildcard characters. How do you use a wild card in an Access query?Use wildcards in queries and parameters in Access. Open your query in Design view. ... . In the Criteria cell under the field you want to use, add an asterisk on either side of your criteria, or on both sides. ... . On the Design tab, in the Results group, click Run.. What is the wildcard character in a SQL query?A wildcard character is used to substitute one or more characters in a string. Wildcard characters are used with the LIKE operator. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column.
